I chose to answer your questions because i... chose to do it U_U.
1. Chakra
Chakra is the very force of life that every individual that exists in the ninja world, our life source. Chakra is being molded in our core and channeled to different parts of our body to empower them, or to release the chakra into different techniques. Chakra is composed by physical and spiritual energy that roots deep inside of us. Through the use of tenketsus(chakra pressure points), ninjas can release their inner chakra outside their bodies and perform ninjutsu.
2. Handseal
A handseal is the type of seal you make in order to focus your chakra and give it properties to pertain a certain technique. Usually the stronger the technique, the more handseals. Not always though, but for complex jutsus, handseals are required. Some ninjas has become so adept with their respective elements of favour that they only need a single handseal for complex jutsus.
3.Ninjutsu
Its the style of fighting almost all ninjas share by utilizing their chakra in fight. This means that they create tools or elemental chakra hone their mastery in battle. Ninjutsu doesn't work without chakra though.
4.Tag
A tag is a jutsu inscribed in symbols and text. Could vary between sealing tags to explosion tags were as one is designed to keep things locked in as the other is meant to blow things up. Basically chakra infused symbols and text. Comes in handy on weapons such as kunais and senbons. Although paper is common to hold explosion tags.
5.Paper tag
Basically a tag on a paper. A paper tag is generally always about explosion tags. Toss them towards your opponent or plant on them, either works great and doesn't require handseals. Fast and easy to use. With enough preparations, Konan almost killed Obito with an ocean of paper tags. Further use of advanced paper tag use was when Tobirama used them with a conjunction of edo tensei which spawned more paper tags for each tag that blew up. That caused a chain explosion that never stopped.
6.Seal
Seals are living in the ocean and eats things that looks like Kisame.

Seals are fuuinjutsu basically. They work by sealing techniques away and lock them. Seals can also be used offensive while its more common to use as defense. Seals can work in different ways. You can seal away techniques and you can also seal away the potential force your opponent could unleash, such as kekkei genkais. Seals also could be used as in terms of transportation, like the seal of the flying thunder god where the user has a seal on a kunai he tosses and teleports to. Much like a tag on the kunai, a sealing tag.
7.Fuuin seal
Basically what i wrote above. Fuuin seals are only used to seal/lock away other techniques or gigantic forces such as bijuus. They can create gigantic and indestructible barriers if used with great chakra reserves.
8. Kanji
Kanji are the symbols that are on tags or seals. Basically the inscription for the technique the tag/seal works with.
9. Contract
A summon contract is a blood-bond that a user makes with their wished summon. A contract requires a summon scroll for it to work. It works with a seal that uses space-time, making the user of the contract able to always summon his animal to the field in an instant.
10. Blood ritual
A kinjutsu/forbidden jutsu. This means you draw out the life of your opponent through spells or witchcraft and steal their power or harm them with torture.
11. Fuuinjutsu
Glad you asked ,P. Fuuinjutsu is sealing jutsu that is used to lock away living creatures, jutsus, objects etc. Along with chakra itself.
