Couple of ways:
1) Add Thread.Sleep(NumberOfSeconds * 1000) between each calls to Process.Start. This is bad - it freezes your UI while the Sleep goes on.
2) Set up a Timer for a 1/10th second interval and handle it's Tick event. Add counters to your app, one for each process you want to start.
In the Tick event, check each tcounter in turn.
If it's zero, do nothing and move on to the next timer.
Otherwise, reduce it by one. If it's now zero, start the process.

When you want to start the processes, just set the counters to the required interval: counter1 gets 1, counter2 gets 1 + 30, counter3 gets 1 + 30 + 30, and so on.
This takes a bit more coding, but it's more friendly for your user, and can be a lot more flexible as well.
