In my right breast I can feel the implant poking out. They are over the muscle and 13 years old. Can I get them under muscle?

 I am sorry to hear about the problem you are experiencing. Often, it is possible to perform the operation you are considering in a single stage (possible to convert sub glandular breast implants in to the sub muscular (dual plane) position). Successful results do depend, to some degree, on the surgeon's experience. Therefore, best to make sure that your plastic surgeon can demonstrate significant experience helping patients with this type of revisionary breast surgery. Sometimes, patients undergoing conversion of breast implant positioning from the sub glandular to the sub muscular space benefit from additional maneuvers such as breast lifting (depending on the position of the breast skin envelope in relation to the position of the sub muscular breast implants) and/or the use of acellular dermal matrix for lower pole support and/or additional coverage of breast implants. Closing off the existing breast implant pocket is a technique utilized to help prevent the breast implant from moving back into its previous space.I hope this, and the attached link demonstrating many relevant  cases, helps. Best wishes.

and improve your current situation.  Depending on what your anatomy is like, the technique will vary.  If your implant is poking out with a palpable tip, you really need to get this done asap.  Most experienced surgeons should be able to accommodate your needs and produce a satisfactory outcome.
