I don't think any of the seven alternatives sound correct.
First off, when dealing with distances, the comparators "longer" or "greater" work better than "larger," "higher," or "bigger." Larger would imply some kind of area or volume; higher implies height or altitude, and bigger is simply too vague, and doesn't sound sufficiently scientific.
However, all seven alternatives seem to imply that the measuring device #1 is capable of measuring a longer distance than measuring device #2, rather than comparing the two measurements themselves.
When A and B are both positive, simply say, "Measurement A is greater than Measurement B," or, "The measurement taken from Interferometer #1 was greater than the measurement taken from Interferometer #2."
When A and B are both negative, use, "Measurement B is less than Measurement A," or, "The measurement taken from Interferometer #2 was less than the measurement taken from Interferometer #1."
Moreover, this assumes that the magnitude is not as important as the real value, which isn't always the case in physics. One might need to say, "The magnitude of Measaurement B was greater than the magnitude of Measurement A," in the case where, say, A = 2, and B = -5.
If you're asking if there is a single set of words to use - irrespective of whether the values are positive or negative - I can't think of a good template to use.
When you use the word group your emphasis should be on the collection of things in the group.
How many people do you have in your group?
When you use the word grouping your emphasis should be on the act of forming the group rather than the group itself.
Which grouping would be better- girls in one group and guys in another, or else adults vs children?

Well, when we say community, we refer to a large number of people or entities, who may be affiliated to many smaller or disparate sub-structures.Community almost always refers to a varied and large audience, yet with certain things, which maybe certain interests, opinions, or religion or ethnicity.
On the other hand, group is indeed most often used for a small number of people or other entities, each of which may or may not be large. Also, a group is not as natural a collection as community. A group maybe formed by some of us just now, but a community arises on its own and comes together, and has more naturally common attributes. Similarly, one can be expelled from a group, if he disrespects the rules, but one cannot be banned from a community per se, unless it is something very artificial like a virtual social networking aggregate that is moderated etc.
E.g. we talk about the international community of researchers of a certain field, say Physics, or the international community of institutional investors (each of which is an institution like a bank and consists of millions of people), whereas we say G8- a group of nations.
