The normal heart rate for adults is between 60-100 beats per minute. However, medications and certain conditions can raise and lower your normal pulse rate. Additionally, people who are very physically fit sometimes have a much lower resting heart rate. See your doctor to determine what a proper heart rate is for yourself personally.
Yes, after a brisk walk such a level is fine - (as long as you are feeling fine.)

Instantaneous Heart Rate is taken by measuring the distance between the R-R interval on an ECG recording. This value tells you how long one heart beat takes. This single value is used to then determine the number of heart beats/minute which is IHR.
If that is your heart rate (135 beats/min) and you have not just rushed up a long flight of stairs, then no. A heart rate should be between 60 and 80 at rest. If you resting heart rate is indeed 135 BPM then it would be sensible to get yourself checked out by a qualified medical practitioner (a Doctor) as soon as possible.
The heart beats continuosuly throughout a person's life. It never stops until death comes.
