So the Uzumaki have Kushina and Karin (with their powerful chains), BSM Naruto, and Mobile Nagato?
Tobirama isn't that much of a factor because he'll get killed by BSM Naruto, and then proceed to help his family against Hashirama.
Hashirama doesn't have a counter to Chibaku Tensei (especially if its the one that was used to trap the 9 Tails - not to mention the CB gets better every single second that passes by).
Even if he (which they doesn't), Kushina would just use her chains on him to distract him while he gets sucked up by CT. If her chains weren't enough for some reason, Karin will use her chains and make Hashirama completely immobile - Karin's chains effortlessly restrained Spiral Tobi's SS from doing anything. Yes, it's not as powerful as Hashirama's, but now add Kushina's (which restrained the Kyuubi) and that should do it, or at least temporarily.
Naruto will distract Hashirama's Wood Dragon and maybe even the Golem too. He'd probably lose to them, but by the time that happens, Hashirama will have been sucked up already - not to mention that nothing stops Nagato from helping Naruto fight those two things while the Chibaku Tensei sucks Hashirama up, but it's not necessary.
