Yes, the Shure FP33 will fit inside the ORCA OR-28 Mini Audio Bag, but there will be some extra space.

I just received my OR-28 a couple of days back. I'm also using it with a Zoom F6, together with a set of wireless transmitters (Saramonics) for my grab-and-go, all-in-one audio rig for most of the video work that I do. The F6 and transmitters fit in with room to spare, like someone else mentioned. I still have space in there for my lav mics and other adaptors, tape, chest straps, stationary etc. I'm looking forward to doing some modifications to make full use of the extra space. Depending on your needs I'd say the extra space can be a blessing or curse because things tend to jiggle around abit if you got nothing to hold them in place.

The Zoom H6 will fit into this bag, but because it has XLR mic connections on the two sides of the unit, you may have difficulty making it work when sources are connected. Access to these connections would also be limited. Perhaps, a reasonably-priced case such as the Zoom PCH-6 Protective Case for Zoom H6 Handy Recorder, BH #ZOZPCH6 could be used until you upgrade to a larger mixer.

No, the ORCA OR-28 Mini Audio Bag is a bit too small for the Sound Devices 833, but the ORCA OR-30 Audio Mixer Bag (B&H # OROR30) and the ORCA OR-330 Sound Bag (B&H # OR330) are both designed for use with the 833. Other compatible options include the Arco AS-A10G Small Bag for Audio Field Recorder (B&H # ARASA10G), the Sachtler Lightweight Audio Bag - Small (B&H # SALWABS), and the PortaBrace MXC-833 Custom-Fit Carrying Case (B&H # POMXC833).You can find more compatible options for cases and bags listed under the "Accessories" tab on the item page for the Sound Devices 833 8-Channel / 12-Track Multitrack Field Recorder (B&H # SO833).

This recorder has eight inputs, you can use all of them for wireless mics if you would like,

The OR-28 is a bit small for the SD 702. ORCA's OR-32 Audio / Mixer Bag (B&H # OROR32) is the right size.

Per Tascam the dimensions on the DR680MKII is - 8.5" × 2.2" × 7.4" / 216.4 × 56 × 188.4 mm The OR-28 internal measurements are - 8.46” x 4.52” x 6.49” making it too small for the OR-28. The OR-280 would be a better fit with internal of 9.44” x 4.52” x 7.87”

The interior of the ORCA OR-28 Mini Audio Bag is 8.5 x 6.5 x 4.5" (215 x 165 x 115 mm) and the dimensions of the Tascam DR-60DmkII Field Recorder are 5.2 x 3.7 x 3.1" (133 x 93.2 x 78 mm) so the DR-60DmkII Recorder will fit inside of the OR-28 Bag.
