To solve the problem of measuring the objects using a ruler, we need to carefully observe each object and determine its length based on the markings on the ruler. Let's go through each part step by step.
---
Step 1: Understand the Ruler
- The ruler is marked in inches.
- Each major division represents 1 inch.
- Each inch is further divided into smaller divisions (typically 8 or 16 smaller divisions per inch, depending on the ruler).

Step 2: Measure Each Object
####
Object 1:
- The object is a small cylindrical item.
- Align the left end of the object with the 0-inch mark on the ruler.
- Observe where the right end of the object falls.
- The right end appears to be just past the 1-inch mark but not quite reaching the 2-inch mark.
- Estimate the exact position: It looks like it is about halfway between the 1-inch and 2-inch marks.
- Therefore, the length is approximately
1.5 inches.
####
Object 2:
- The object is a long, thin item.
- Align the left end of the object with the 0-inch mark on the ruler.
- Observe where the right end of the object falls.
- The right end appears to be just past the 4-inch mark but not quite reaching the 5-inch mark.
- Estimate the exact position: It looks like it is about three-quarters of the way between the 4-inch and 5-inch marks.
- Therefore, the length is approximately
4.75 inches.
####
Object 3:
- The object is a short, rectangular item.
- Align the left end of the object with the 0-inch mark on the ruler.
- Observe where the right end of the object falls.
- The right end appears to be just past the 2-inch mark but not quite reaching the 3-inch mark.
- Estimate the exact position: It looks like it is about one-quarter of the way between the 2-inch and 3-inch marks.
- Therefore, the length is approximately
2.25 inches.
####
Object 4:
- The object is a coiled spring.
- Align the left end of the spring with the 0-inch mark on the ruler.
- Observe where the right end of the spring falls.
- The right end appears to be just past the 3-inch mark but not quite reaching the 4-inch mark.
- Estimate the exact position: It looks like it is about halfway between the 3-inch and 4-inch marks.
- Therefore, the length is approximately
3.5 inches.

Step 3: Summarize the Measurements
1. Object 1:
1.5 inches
2. Object 2:
4.75 inches
3. Object 3:
2.25 inches
4. Object 4:
3.5 inches

Final Answer
\[
\boxed{1.5, 4.75, 2.25, 3.5}
\]
