I need to pump up a tire, but the bike pump for some reason has a lot of water in it, mist coming out when I pump. I’m wondering if there would be any damage to the inner tube if some mist got inside.
No damage, but the moisture will never leave the tube. I would keep pumping the pump on its own, without a tube, until the air coming out of it is dry. Or, obtain another pump.

I suppose that you could remove the core (with a tool like the Park Tool VC-1, or whatever other tool you like) from the tube and leave the tube out in the sun to dry. The tube is rubber, valve is usually brass or something that is pretty corrosion resistant. Same goes for the pump … just leave it out in the sun. Depending on the manufacturer, you may be able to disassemble it and speed the drying process up.
You should also consider cleaning your pump. You should be able to open it in the back, pull the piston, clean out all the moist with paper towels, let the hose and everything dry in a dry and warm environment and regrease it with standard bike grease before reassemblying.

Maybe you should just fill your tire with water in stead of air and then let us know how comfortable that rides.

I pumped out most of the water, a lot of mist came out and no more is, and I pumped up the tire. Hope its fine

A little moisture mist getting into the tire won’t damage the inner tube. It could cause corrosion over time if a lot of water gets in but a small amount isn’t an issue. Letting the pump dry out or purging it before pumping should be enough.
I used to have problems with drilled rims, probably due to snow and deep puddles. I then switched to regular rims and haven’t had the problem since.
