See below for more information. Q: Can I overwrite my current app without removing it? A: Yes, it is possible. In order to accomplish this, you need to sideload the IPA with the same Apple ID that your previously sideloaded app is with. If you previously manually set a custom bundle ID, you need to use the same ID again.
Q: How many apps can I sideload? A: iOS 7, 8, 9: You can sideload as many apps as you like on your device.
