Hi team, lets say we already implement a namespace.. FYI Experiment 1 is gonna take 6 month experiment period while Experiment 2 is probably 1-2 month experiment period. After 1-2 month, we finish up the Experiment 2 My question is, can we use the population that already spaced from the percentage of Experiment 2 to be reuse for another new setup experiment? basically in simple words same users who were witnessing Experiment 2 should witness this new experiment now.

Yes, you can. Within the namespace the users will be rerandomized with every new experiment

but i don't want re-randomization, so basically Experiment 1 is still running so these users should stick with experiment 1 only the new experiment should be visible to the rest remaining percentage of people only
is this ensured?

Well, depends on what you want to do
You can run run them in parallel if you like, without the namespace

Ok
The division of users by the namespace happens first, so those users in exp 1s namespace will stay in that group
Same with the other half of that namespace, if you end an experiment in that space, you can re use that space.

ohh so there will be no mix-up right?...so the population which was previously witenessing experiment1 will continue to witness that experiment even though experiment2 is stopped and a new experiment is swapped in on that particulat percentage of namespace?
