I am not aware of any instrument having 88 strings. Pianos generally have 88 keys but there are more than one string for each key. The orignal answers below talk about the number of keys as well as the number of strings on a harp, but no harp has 88 strings.
=======================================================
Piano (para 1). Harpsichord (para 2). Harp (para3). Organ (para 4) The keys are connected to the hammers which in turn hit the strings. Open a piano and have a look! Some Pianos do not have 88 keys. They normally range from 86 - 88 keys.
Also Harpsichords sometimes have 88 keys but They generally have 4 to 6 octaves so, around 48-72. Harpsichords with double manuals, have the double of keys, so 96-144.
Harps also sometimes have 88 keys but it varies with each harp. Non-pedal harps can have anywhere from 20 to 40 strings. Usually harps that have 20 to about 30 strings are referred to as lap harps. A good size lap harp has about 22 to 24 strings. A standard folk harp has 36 strings, thought the more commonly preferred size is 34 strings. Pedal harps can have anywhere from 40 to 48 strings.
The Triple Strung harp or Welsh harp has 88 strings the same amount of strings as keys on a piano, but these are exceedingly rare, so I wouldn't worry about this one.
Organs vary the most. Some Organs have one Keyboard, others have 2, 3, 4 and sometimes 5! The present main console is normally four manuals of 61 keys each, so the total is 244 manual keys. And there are 32 pedal keys.

The lute's strings are arranged in courses, usually of two strings each, though the highest-pitched course usually consists of only a single string, called the chanterelle. In later Baroque lutes 2 upper courses are single. The courses are numbered sequentially, counting from the highest pitched, so that the chanterelle is the first course, the next pair of strings is the second course, etc. Thus an 8-course Renaissance lute will usually have 15 strings, and a 13-course Baroque lute will have 24. The number of strings a lute has depends on the type of lute; it could have as few as eight or as many as thirty-five, with other possible variations. The links below might prove helpful.
