If you have a full size SP5 and not the "K" model then you will want this instead:

No, it will not unless you source some sort of custom adapter as this is meant for the MP5K and exact clones of the MP5K. This is the fit information for this unit provided by SB Tactical:
FIT: HK MP5/MP5K Reverse Stretch Clones
You would need this model instead for a full size PTR 601:

No, none of the MP5 braces will work for a Ruger Charger. Assuming you have a model of Ruger Charger that has the picatinny back end, here are two SB Tactical braces that will work:

This will likely fit, but may not be perfect as this is meant for MP5K clones. How close the clone is to an actual MP9K will determine how well this brace fits. There have been many end users who have been able to make this work for their PTR 9kT 603.

No, none of these options will fit the KP9.
No, this brace will not fit the Stribog. There is a manufacturer who offers an adapter so that you can use this brace:

But we do not carry that adapter. You will need to source it on your end.
