Does time dilation have an effect on them traveling up in space?

By age I mean, biological age, like 30 years old or 60 years old on Earth.

No, not that noticeably. I remember reading on a NASA webpage a few years back that if twins were born and one was taken to the ISS and one lived on earth at sea level, the one on the ISS would live 1/5th of a second longer if both had a life expectancy of 100 years. To age slowly enough to notice, they would have to travel way faster. Like 3/4 the speed of light.

Yes they do. Though by no recognizable amount. In an interesting experiment in attempt to prove relativity, a clock was put into orbit around the earth. It was put up for about a month, at speeds as fast as the ISS. The difference in time was 3 microseconds. That is, three microseconds less. So that mean that if the astronauts were in orbit for 10,000 years, they would be 1 second younger than people who were on earth for those ten thousand years. So they age slower, but by no noticable age.

There's some heavy math going on here. Since they are travelling rather fast around the Earth (17000mph+), they are aging slightly slower than the rest of us. However, since they are also further away from Earth's core and in a slightly weaker gravity field (not to be confused with freefall), they are aging a little bit quicker. It might be a wash.
It has been proven that satellites do experience a wee bit of time dialation, but we're talking only billionths of a second every year. Barely measurable.

Nothing. It would float together with the space station. The hammer has the same speed as the space station when it is inside. Dropping it outside doesn't change its speed too much. As there is no air in space to slow it down, the hammer would continue to move at its original speed: that of the space station.

first you must define age.
the passing of time,
or free radicals released when converting calories, resulting in damaged cells.= causing old age symptoms
the first, yes. I believe
the second, no. depends on what they eat
I've heard if you have two watches (same time) and take on up to the ISS and leave one on earth, the one in the ISS will be a few 1/10s of a second behind.
I think the problem is common with satelittes since they spend more time up there.
This wouldn't greatly effect the aging process, but yes. it does slightly

Yes, but less than a second. You'd have to be moving much faster for time dilation to make any significant difference.

Yes, so do you while travelling in a jet but the amount of time involved wold be only in micro seconds.

You might think so but the 0 gravity plays havoc on your bones. Bone density loss is aging in it self

Yes because they are travelling faster than we are so when they return to our frame of reference we really do measure them to be younger.

yes they will be youger its something about the rotations changing the legth of the years
