That's an amazing bunch, especially to start out with. There are people who'll say "there's no rules just try them in every order and see what you like", but that isn't particularly helpful when there's 5040 ways of ordering 7 pedals and there definitely ARE at least guidlines.
The general guideline for effect types is: Pitch > Drive > Filter > Modulation > Time
The ditto is an in interesting one, it depends on what you want to do with it. Do you want the ditto to play loops with effects on while you play other stuff over it? (The end) Or do you want to be able to add effects on to loops as they're playing? Same with the tuner, do you want it to act as a master mute (at the very end) or do you want to be able to tune while a loop is still playing? (the very start).
Compressor again depends on what you want from it, if you're wanting it for peak limitng then it could go straight after the MF101 and the FI or at the end, if you're wanting it for general smoothing/colour then it should probably go at the start, but beware if you have it set too heavy it'll make the MF101 less lively.
If it were me the first thing I'd try would be: Tuner > Cali76 > Octavre > Doom > MF101 > FI > Ditto
