In this section, I'll be listing Hashirama's techniques that can be countered by Nagato, and why:
NOTE: I'm using Yamato's techniques. Just imagine them on a larger scale.
1. Mokuton - Forest Genesis

As shown, this technique obviously creates a huge forest that not only grows anywhere, but it also attempts to bind the user (shown by it attacking Hiruzen). IMO, this technique will be quite simple to beat by Nagato, even without the use of Preta Path (which can simply absorb it). As shown in his fight with Naruto and co., Nagato can use Shinra Tensei while still immobile, shown here:

With this, Nagato can easily push away any wood binding him. It can be noted that Kabuto forced Nagato to use it, but Amaterasu =/ Mokuton in terms of damage to the body like that. Binding by wood will not kill Nagato, therefore he'll still be able to use Shinra Tensei to blast it away. And with the Deva, Asura, and Preta paths, Nagato can easily dispatch the entire forest.
2. Hokage-Style Sixty-Year-Old Technique — Kakuan Entering Society with Bliss-Bringing Hands
This is a technique used by Yamato to bind a Bijuu's chakra, which Nagato has none of. So it should be no issue.
3. Wood Release: Wood Spikes Ring

A technique used by Yamato, and also probably Hashirama. A Shinra Tensei should easily be able to blow it away, even if the spikes are in motion.
4. Wood Release: Four-Pillar Prison Technique

Asura path's missiles should be able to easily blow this up. Or the Preta Path can absorb it. OR Deva Path can just blow it away. No issue here.
5. Wood Release: Great Forest Technique

A technique that transforms the arm into wood and extends it as maneuverable spikes. A deadly technique, though Nagato can easily counter it. Nagato can simply use the Preta Path on this technique to absorb it, or use the Asura Path to grab it with mechanical arms, as shown below:

6. Wood Release: Smothering Binding Technique

There are two counters to this. One is the simple Shinra Tensei to blow it away. Or Nagato can use the Preta Path to absorb all the Ninjutsu around him, as shown:

7. Wood Release: Wood Locking Wall

This is a defensive jutsu that doesn't really pose much of a threat to Nagato. He can easily blow it up using his Asura Path, and that's only one option. This is what Nagato can do to this jutsu to blow it up:

8. Wood Release: Jukai Koutan

Nagato has a couple of counters to this. One is he can absorb only the wood in his vicinity, so as to remove any nearby threat. OR he can use the Asura Path and fire missiles everywhere to counter and stop the wood. Or he can simply use Shinra Tensei and send everything flying away from him.
9. Wood Release: Advent of a World of Flowering Trees

This technique poses a decent threat to Nagato. But, as shown, it can be avoided by flying up and away from it, as shown by the Kages floating up above it, through Gaara's sand. Also, as long as it isn't inhaled, it'll have no effect on a floating Nagato, and we all know the Deva Path can fly, letting Nagato avoid this technique. Then, he can just use Shinra Tensei from the air to get rid of all of it:

10. Healing without handsigns
A good move indeed. But Hashirama was still bloodied and exhausted after his fight with Madara, showing that he can't completely heal anything. So a Chibaku Tensei, Asura Path missiles, or any other destructive technique (Nagato has all elements) can easily damage Hashirama by a good amount.
