Hi there!
Yes, it is fine for the other testicle to hand normally.
There are no recommended positions. You can choose whatever you are comfortable with.
Yes, it is fine to spread/ stretch legs after the surgical site has healed.
Yes, it is fine to do activities that mildly tense up the region; while activities such as abdominal exercises etc. that grossly tense up the region are best avoided.
Hope the information is helpful.
Take care!
