Such as after the milky way galaxy collides with andromeda, would the Sun be able to still maintain life; considering it would still be a yellow dwarf and we'd still be on Earth?

Sun is all for us. Eevrything on Earth for survival & sustenance depends on the Sun. It is the whole & sole source of all energy.
Galaxy's influence on Solar system is not readily discernible. So, I think Solar system would survive without a galaxy.
Collsion of two galaxies is not like that of two rigid bodies. It is like one cloud passing into another. Between the stars there is enormous emptiness. In the process of passing into one another the two galaxies make their constituent stars subject to gravitational pulls that might be vicious in some cases. But the time scale for such happenings is on the order of a million years.

No, We wouldn't. As the other guy said, All food chains start with a producer, and without the sun, they would not be able to convert oxygen and water into glucose via photosynthesis. Therefore, they do not get the required nutrients to live, and as a result, the food chain stops and no trophic levels above would exist, and all life on earth and on other planets (if there is any) would cease to exist.

Common sense says that nothing lives in a figurative vacuum. The sun is part of a bigger picture. It's also spinning around a center, the Milky Way's center. Who knows what would happen? The whole universe is full of checks and balances. Once you take away that balance all kinds of things are plausible, like the sun's solar flares dying or increasing in strength, for example.

No, we wouldn't. The sun helps plants grow. Plants provide oxygen and food, which we clearly need. The sun also helps to give us Vitamin D, which we need in our systems. So when the sun explodes, the world will most likely end.

Sure. As the other answer said, the sun is important to all life on earth. But the other stars aren't. So if we still had the sun, but not the other stars, we'd be fine.

Assuming that our solar system isn't affected by wayward gravitational pulls as the two galaxies combine, absolutely.
